PERMUTATION' ELECTRIC SWITCH.

Specification of Letters Patent.

Application. filed February 6, 1919. Serial No. 275,350.

To all whom it may concern: 7

Be it known that I, THOMAS CAPPAREILA,

a cirtizen'of the United States, residing at New York, in the county and State of New York, have invented certain new" and useful lniprovements in Permutation Electric Switches, of which the followingis afull, clear, and exact specification.

p This invention relates to." permutation electric switches, and has fOIfitS object to simplify. and improve tumbler disks and the electric connections to and through them, so

that such switches may be manufactured at a; reduced cost and givesuperior results'in use. i

A special object is to combine the step by step retaining arms for the tumbler disks with the circuit connect'ons so that said arms will serve the do ble function and the contact armson the same side of the de- I vice. Other objects will appear as the description proceeds.

The invention will be first hereinafter described in connection with the accompanying drawings, which constitute part of this specification and then more specificallydefined in the claims at the end 'of' the description.

- In the accompanying drawings, wherein similar reference characters are usedto designate corresponding parts throughout the several views I Figure lis a front elevation of the switch tion- ='Fig.'af.3 is a section through the disks and arms'as'well as the casing, the section being takenon the line III'III of Fig. 2,'and

showing the circuit wires connected to the single end the device. I I 4 Fig. 4 is a detailed face view ofIone of arms at the front and back of I the tumbler disks, showing the radial grooves thereln, and

Fig. 5 is a rear elevation. of the switch with the back of the casing removed.

The casing of the switch is preferably made round, as shown in Figs. 1 and 5, and

I comprises front and back portions ,1 and 2,

respectively, having slip connection at 3. 'It will be understood that the switch may be used Wherever it can be utilized to advantage, but it is especially designed for controlling the power circuits of automobiles to prevent the unauthorized use of cars.

A frame 4 has its legs secured to the front member 1 of the casing, as by solder 5, and a shaft 6 is journaled at 7 in said'front member 1 and at 8 in said frame. On the front end of the shaft 6 there is an operating knob or handle 9 on the outside ofthe casing, while within said casing and between the front portion 1 thereof and the frame Patented July 22, 1919. i

4 there are arranged a plurality of tumbler disks, three being shown at 10, 11 and 12. One of said disks, the middle one as shown, has a hub portion 110 through which a clamping screw 13 is passed to fix it to the shaft 6. The front disk 10 is suitably spaced from the dial 20 by a washer 14.

-The disks 10 and-.,1-1 may be spaced apart.

by the hub 110,-w-hile the disks'l l and 12 are spaced apart by one 'or more Washers also indicated at 14, and another of said washers is placed between the'rear' disk 12 and the frame or bracket 4. A washer 15- may be placed between the rear face of the frame 4 and the casing.

The adjacent faces of the disks are equipped with axially projecting pins or lugs 18 which may be placed at any desired points on said disks for causing the end disks 10 and 12 to be turned at the proper times by the middle disk 11,'as is common in permutation devices, the end disks being loosely mounted on the shaft 6 on'which the middle disk 11 is secured to turn therewith by the screw 13 or otherwise. The marginal portion of one lateral' face'of each- .disk is formed with. radially-arranged grooves 16,,

back .member- 2 of the.

tively at the bases of one and the connectors 17 are placed respecof said grooves in each disk, as shown in Figs. 3 and 4. A pointer 19, is carried by the shaft 6 in front of the dial 20 and preferably below a crystal 200 for indicating the movements of said shaft which is rotated: by means of the knob 9 to adjust he quired combination.

"23 from the lump 28. 'The contactarm tumbler disks to the re- Moiinted in the casmg, preferably on one' end portion of the frame OnbracketA is a plate or strip of insulating material 23 on which are mounted contact arms 24, 26, 27,

The contact arm 24, at. the extreme rear or back of the casing, isattached to the insulating plate 23, by a lump 25 of. conducting materlal, such as solder or other metal, and to it is connected one of the circuit wires2l. The contact'arms 26 and 2-7 are both attached to alump 28 of conducting metal which is spaced from the lump 25 along the insulation plate 23.- The" contact arm 29 and 30 are similarly both connected to a lump 31 of conductingmetal which is spaced alongth insulating plate 9 is connected to a lump 33 of conducting metal which is attached to the insulating plate 23 in spaced relation to the lump 31, and to said arm is connected the other circuit wire 22, as shown in Fig. 3. It will thus be seen that the contact arms 26, 2'7 and 29, '30 are electrically connected together in pairs, while the contact arms 24 and '32,

which are connected to the circuit wires, are

insulated from said pairs of connected arms,

' the arm 24 engaging the rear face of the and that "the said connected pairs of arms are insulated from each other by the plate 23. The contact arms-bear upon the opposite lateral faces of each of the tumbler disks,

disk 12,.the arm 26 engaging the front face of the same disk, the arms 27 and 29 engaging the rear and front faces, respectively of the disk 11, and the arms 30 and 32'engaging the rear and front faces, respectively,

. of the disk 10. As shown,the front face of of the arms may making close,- contact with disks. The arms of the disks. The'ofiset ends 34 of theother arms are adaptedpto .contact,with the conneotors 17 wherethey are arranged at-the' bases of o'neof the grooves 16 in'each disk,

24, 27 and '30, which engage with a predeterminedcombination to bring the connectors 17 of all of the disks into contact with the arms which engage the opposite faces of all of the disks, the circuit will be completed through said arms,iconnectors and lumps '25, 28, 31 and 33 ofconducting metal from-one ofthe circuit wires 21 to the other-of said circuit wires 22. The circuit may be traced as 'follows: wire 21, lump 25, arm 24:,connector 17 in the disk 12, arm 26, disk 11, arm 29,' 'lump 31, 3111130, connector 17 in disk 10, arm 32, lump 33, wire 22. The arms 26 and 27 and arms 29 and 30 are shown in contact along theirgmiddlej portions, so that the circuit can pass directly from arm 26 to arm 27 and from arm 29 to arm 30, instead of passing through the -'1 umps 28 and 31, but the,' results will be the same as if said arms were not in direct contact.

It will be observed'that the oifset'ends 34: of the arms'which engage the frontfaces of the several disks serve the double'func tionof conductors in the, circuit, as they so that when the disks are turned to agree t5 lump 28, arm 27, connector 17 in contact with the connectors .17'and carry 4 the current, and of step by step retainers for.
